Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT3G11540 SPINDLY gibberellin Deletion of 3?end Encodes a N-acetyl glucosamine transferase that may glycosylate other molecules involved in GA signaling. SPY may play a central role in the regulation of GA/cytokinin cross talk during plant development.
